To estimate maximum active sessions on my oracle database is reasonable to the approach?

For estimating the *maximum concurrent connections* on my oracle database server I did the some work as follows:

• Acquiring *Average Active Sessions* & *Logic CPUs* in Real Time;
• Retrieving the *current concurrent connections* on view *"v$session"*;

Via the above two steps I've got some data, such as, aas value is *3.66* and logic cpus are *192*. Next I've got the current concurrent connections (*61*) by running this SQL statement: *select count(*) from v$session where status = 'ACTIVE';* Thus I am able to estimate the maximum concurrent connections using the following formula: aas value / logic cpus = current concurrent connections / maximum concurrent connections. That is to say, *3.66 / 192 = 61 / maximum concurrent connections*, so which is *3200*. Is it reasonable to this approach?
